The Bennu bird was the mythological phoenix of Egypt. The Bennu was pictured as a grey, purple, blue, or white heron with a long beak and a two-feathered crest. Occasionally the Bennu was depicted as a yellow wagtail, or as an eagle with a magnificent spread of red and gold feathers. The Bennu is said to have been born through the raging flames, which was burned on a holy tree in one of the sacred precincts of the temple of Ra. Another version of how it was born was through the very heart of Osiris (Egyptian god of life, death, and fertility). The Bennu was linked with the rising of the Nile, resurrection, creation, renewal and the sun.
